add support for other content addresses #33
Description
ENS supports ipfs but also bzz, onion and onion3 content hashes. It would be nice to have support for them too.
For bzz it's easy, because it's exactly like ipfs. There is a public gateway (swarm-gateways.net) and local swarm node could be available at localhost:8500.
For onion addresses no config is required. Just forward to it. (it still requires configuration, but it's not in the scope of almonit, I think)
